It may seem counter-intuitive to not also liberally lather your yoni with shower gel. But soap will cause more harm than good.
The vagina requires a certain pH to remain healthy and soap destroys its delicate environment.
"Soaps have colourants, fragrances and preservatives. These all change the pH environment of the vagina - which is then conducive to infections that are pH dependent," says Dr Moyra Stein, a GP in Cape Town with a special interest in women's health.
